The indictment did not provide any new details on what might have happened to Porter, who had struggled with cocaine addiction.

Running
Some of Kenya's most celebrated runners say they are receiving death threats because of rumors they are involved in the ethnic violence that has swept the nation following a disputed election.
Many gathered from across the country this week in the western town of Eldoret. The meeting ended with a statement intended to dispel the rumors.
During the meeting, William Mutwol, a bronze medalist in the 3,000-meter steeplechase at the 1992 Olympics, received another threat in a text message.
"We want your head," the message said.
About 700 people have been killed across the country, including former Olympic runner Lucas Sang. Marathon runner Wesly Ngetich was shot with an arrow and died on Monday, but it was not clear whether his death was linked to the election violence.

An art gallery wants to unveil a memorial depicting fallen Kentucky Derby winner Barbaro near New York's Central Park this spring, close to where a carriage horse died after it was startled by a street musician's drum and ran into a tree.
The sculpture by artist Daniel Edwards depicts the popular colt on his back, a No. 8 saddle cloth draped over his belly and his hooves in the air, according to a statement from the Leo Kesting Gallery.
The gallery plans to unveil the statue April 30 to raise awareness for legislation urging mandatory disclosure of race-related horse injuries and fatalities.
"This has nothing to do with us, nothing whatsoever," Barbaro's co-owner, Gretchen Jackson, said of the memorial. "This is not the kind of thing you'd really want to see.
